Abstract (en)
An optical semiconductor apparatus having no polarization dependency and an optical communication system using the semiconductor apparatus are provided. In an optical communication system wherein a signal is demultiplexed by using a semiconductor waveguide type filter disposed on a receiver side, two semiconductor lasers disposed on a transmitter side modulate two light signals having different wavelengths using a common modulation signal and transmit the modulated light signals. One of the different wavelengths is accorded, for example, to the TE mode transmission wavelength of the filter, and the other is accorded, for example, to the TM mode transmission wavelength of the filter. On the receiver side, lights at different wavelengths may be branched into two light portions and the branched light portions may be respectively detected by two photodetectors. <IMAGE>
